Explanation:
Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.
1 atm = 760mmHg
= 760torr
= 101325Pa
= 101325Nm⁻²
1mmHg = 1torr
1Pa = 1Nm⁻²
101.325 kPa and 101,325 Pa are the same
1000Pa = 1kPa
101,325 Pa and 1 atm
1atm and 101.325 kPa
Answer:
See explanation and image attached
Explanation:
The reaction of (R)-2-chloro-3-methylbutane with potassium tert-butoxide yields a monosubstituted alkene .
Since the base is bulky, the Hoffman product predominates because attack occurs at the less hindered carbon atom to yield the major product as shown.
The alkene reacts with HBr at the secondary carbon atom to yield a carbocation intermediate which is flat and planar. Attack on either face of the carbocation yields a racemic mixture of the (2R) and (2S) products.
Rearrangement of the carbocation to yield a tertiary carbocation gives the 2-bromo-2-methyl butane product as shown in the image attached.
Answer:
CO2 (Carbon Dioxide) has a negative impact on environment.
Explanation:
CO2 is a product of combustion of Methane
Answer: 0.0106 mol of N in 0.233g of N2O
Explanation:
To solve this you find out how many mol of N2O you can multiply that by 2 to find the mol of N. There are 2 N for every one molecule of N2O.
To do this, you can use the Atomic Mass Unit of the atoms to find the mol. 1 mol of hydrogen has weights 1 gram, hydrogen has a atomic mass unit of 1. Atomic mass unit short hand is amu.
For molecules if you take the total of amu for each atom in the molecule and add them together you will have the weight of the molecule in amu.
The amu can be converted into how many grams are in one mole.
N is nitrogen which has an amu of 14.
O is oxygen which has an amu 16
2 * 14 + 16 = 44 amu
1 mol of N2O is 44 grams.
0.233g / 44 g / mol = .00530 mol of N2O
There is 2 N in each mol of N2O which means that .00530 mol * 2 = 0.0106 mol of N
There are 0.0106 mol of N in 0.233g of N2O
